Condensing boilers | Jeremias® Exhaust Systems

The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gasses are cooler and hence the maximum condensing happens in the chimney. The condensate then flows along the internal wall of the pressure-tight pipe, and back to the boiler for disposal.
